Body
Use asynchronous programming model which allowing some portion of code to be executed on a separate threads. There are three style of Programming with APM <ol> <li>Wait Until Done Model</li> <li>Polling Model</li> <li>Callback Model</li> </ol> Based on your requirement and result you can choose the model which is more appropriate. For instance, let us say you can to read the file and wait until done and sample code is <pre><code> byte[] buffer = new byte[100]; string filename = string.Concat(Environment.SystemDirectory, "\\mfc71.pdb"); FileStream strm = new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read, 1024, FileOptions.Asynchronous); // Make the asynchronous call strm.Read(buffer, 0, buffer.Length); IAsyncResult result = strm.BeginRead(buffer, 0, buffer.Length, null, null); // Do some work here while you wait // Calling EndRead will block until the Async work is complete int numBytes = strm.EndRead(result); // Don't forget to close the stream strm.Close(); Console.WriteLine("Read {0} Bytes", numBytes); Console.WriteLine(BitConverter.ToString(buffer)); </code></pre> But creating your threads are not necessary or suggesting, .NET supports a built in thread pool that can be used in many situation where you thinking to create your own threads. Sample code <pre><code>static void WorkWithParameter(object o) { string info = (string) o; for (int x = 0; x < 10; ++x) { Console.WriteLine("{0}: {1}", info, Thread.CurrentThread.ManagedThreadId); // Slow down thread and let other threads work Thread.Sleep(10); } } </code></pre> Instead of creating a new thread and controlling it, we use the ThreadPool to this work by using its QueueWorkItem method <pre><code>WaitCallback workItem = new WaitCallback(WorkWithParameter)); if (!ThreadPool.QueueUserWorkItem(workItem, "ThreadPooled")) { Console.WriteLine("Could not queue item"); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
